Python

A python is a constricting snake belonging to the Python (genus), or, more generally, any snake in the family Pythonidae (containing the Python genus).

Python (nuclear primary)

According to researcher Chuck Hansen, the W34 Python was a gas-boosted fission primary used in several designs of American thermonuclear weapons.

Primary is the technical term for the fission bomb trigger of a thermonuclear or fusion bomb, which is used to compress, heat and ignite the fusion fuel in the thermonuclear secondary.

Hansen's research indicates that the W34 Python primary was used in the US B28 nuclear bomb, W28, W40, and W49, and as a boosted fission warhead without a thermonuclear second stage in several other weapons. These were the Mark 45 ASTOR wire-guided 19-inch, submarine-launched heavyweight torpedo; the Mark 101 Lulu nuclear depth bomb; the Mark 105 Hotpoint laydown bomb.

Additionally, an anglicised W34 Python known to the British as 'Peter' was manufactured in Britain as the primary for Red Snow, itself an anglicised W28 warhead. Peter was also proposed as a replacement for the Red Beard warhead housed in a Red Beard carcass, and as the Violet Mist nuclear land mine for the British Army in Germany.

Python (Efteling)

Python is a double-loop Corkscrew roller coaster in the Efteling amusement park in the Netherlands. When it started operation, it was the largest steel roller coaster on the European mainland.

History and details

With Python, Efteling started the implementation of a new strategy: development from a fairy-tale forest into an all-round amusement park. This change led to many problems with the local community. Environmentalists tried to get the building permit withdrawn, and the park's neighbors feared more problems arising from growing visitor numbers. Because of the likely noise pollution, the highest court of public justice ordered the construction to be stopped. After some time, construction could recommence, but legal problems continued for several more years.

In 1995, when operating hours were extended until 10 pm, the coaster's 45-decibel noise level became a problem once more. Plans were submitted to the local municipality, describing an extension and complete renovation of the coaster, which would reduce the noise substantially. Due to the high cost, the funds were allocated to the construction of a new enclosed (to reduce noise problems for the park's surroundings) roller coaster, Bird Rok.

.web

.web is a generic top-level domain that will be awarded by ICANN to one of seven registry applicants. The .web TLD will be in the official root once ICANN awards the registry contract.

Historic information about .web

.web was operated as a prospective registry, not in the official root, by Image Online Design since 1995. It originated when Jon Postel, then running the top level of the Domain Name System basically single-handedly, proposed the addition of new top-level domains to be run by different registries. Since Internet tradition at the time emphasized "rough consensus and running code", Christopher Ambler, who ran Image Online Design, saw this as meaning that his company could get a new TLD into the root by starting up a functional registry for it. After asking and receiving permission from IANA to do so, IOD launched .web, a new unrestricted top level domain.

Since then IOD has tried to get their domain into the official root through several plans to admit new top-level domains. Several new-TLD plans in the late 1990s, including Postel's original proposal, failed to reach sufficient consensus among the increasingly contentious factions of the Internet to admit any new TLDs, including .web. When ICANN accepted applications for new TLDs in 2000 which resulted in the seven new domains added soon afterward, IOD's application was not approved; neither was it officially rejected, however, since all unapproved applications remain in play for possible future acceptance. A second round of new TLDs, however, was done entirely with new applications, and only for sponsored domains (generally intended for use by limited communities and run by nonprofit entities). The .web registry remains hopeful, however, that their application will eventually be approved. On May 10, 2007, ICANN announced the opening of public comments towards a new, third round of new gTLDs, a round in which IOD has not participated.

Web (differential geometry)

In mathematics, a web permits an intrinsic characterization in terms of Riemannian geometry of the additive separation of variables in the Hamilton–Jacobi equation.

Formal definition

An orthogonal web on a Riemannian manifold (M,g) is a set of n pairwise transversal and orthogonal foliations of connected submanifolds of codimension 1 and where n denotes the dimension of M.

Note that two submanifolds of codimension 1 are orthogonal if their normal vectors are orthogonal and in a nondefinite metric orthogonality does not imply transversality.

Alternative definition

Given a smooth manifold of dimension n, an orthogonal web (also called orthogonal grid or Ricci’s grid) on a Riemannian manifold (M,g) is a set of n pairwise transversal and orthogonal foliations of connected submanifolds of dimension 1.

Remark

Since vector fields can be visualized as stream-lines of a stationary flow or as Faraday’s lines of force, a non-vanishing vector field in space generates a space-filling system of lines through each point, known to mathematicians as a congruence (i.e., a local foliation). Ricci’s vision filled Riemann’s n-dimensional manifold with n congruences orthogonal to each other, i.e., a local orthogonal grid.

Oracle Developer Suite

Oracle Developer Suite is a suite of development tools released by the Oracle Corporation. The principal components were initially Oracle Forms and Oracle Reports, although the suite was later expanded to include JDeveloper amongst others.

History

In the early 1990s, Oracle had two complementary, but quite different tools - SQL*Forms and SQL*ReportWriter. Both were character-based and there was some integration between the two although they were sold as separate products. The developer interface became more similar over time and they were eventually grouped together as Oracle IDE (Integrated Development Environment).

The suite was renamed to Oracle Developer and then to Oracle Developer/2000.

As with most products that had 2000 in their name, this was dropped after 1999 and the suite was renamed Oracle Developer Suite. Tools such as JDeveloper and Oracle Designer were added over subsequent years.

Most of the component parts of Oracle Developer Suite are now part of what Oracle calls Oracle Fusion Middleware.
